【Abstract】 The electrochemical polymerization of azure at glassy carbon electrode in phosphate buffer solution and the properties of the polymerization films have been studied. The poly(azure Ⅰ) modified electrode exhibits three peaks over the potential range of +0.8～-0.8 V ( vs .Ag/AgCl). The peak potentials are E p 1 =+0.123 V, E p 2 =-0.432 V and E p 3 =-0.125 V ( vs .Ag/AgCl) respectively. The poly(azure Ⅰ) modified electrode shows a good electrocatalytic activity towards hemoglobin reduction in 0.25 mol/L H 2SO 4 solution.The linear range between concentration and current is 0.5～60 mg/L. The linear regression equation is I p=1.002×10 -5 +0.156×10 -5 C, R =0.9995. The mechanism of electrocatalysis toward hemoglobin reduction has been studied.更多还原
